To all whomit may concern:

Beit known that I, ALEXANDERW. COP- LAND, residing at Detroit, in the county of Wayne and State of Michigan,`a citizen of the United States, have invented certain new and useful Improvements'inDough'and Cracker Handling` Machines, of which the following is a s eeification, reference being had therein to t e accompanying drawings.

' The invention relates to new and useful improvements-in sheet dough and cracker handling machinery, and the invention con-` sists in the construction of amachine designed to takeout dough as it comes for 1nstance from a cracker cutting machine, delivering the'cut dou h into an oven, and also for removing the ba ed goods from the oven. Theinvention also consists in combining the loading and unloading mechanism with a single actuating device so that the oven may be simultaneously charged with the ldough to be baked and the previously baked goods unloaded. n

The invention further consists in the construction of the loading mechanism, and also in the construction of the unloading mechanism, and further inthe construction, ar-

rangement and combination of the various' parts as more fully hereinafter described and particularly pointed ou-t in the' claims.

In the drawings, Figure 1 is an end elevation of my improved device showing it adjacent to a reel oven, the partsbeing in their outermost position. Fig. 2 is a section through the loader and the unloader and the charge shelf showing the parts in their innermost position. Fig. 3 is a plan view of Fig. 1, some of the arts being broken away for clearness ofi ustration. Fig. `4 is affront elevation of the machine as it stands in front of the oven. Fig. 5 is an elevation looking from the opposite end to that illustrated in Fig. 1, and showing also the oven actuating mechanism in elevation.` Fig. 6 isan enlarged elevation ofthe vice. Fig. 7 is an end elevationV thereof. Fig. 8 is a plan view,

1 represents the front Walliof a reel oven,

2 the -reel of the loven, and -3V and 4` shelves therein. .The reel is supported upon the shaft 5 in the usualmanner. Upon the'end of the shaft 5 is the wheel 6 having a radial` slot 7, Figs. 5, 6 and 7, which is adapted to.

be engaged bythe pins" 8 on the wheel/9i,

secured to the shaft 10. vOn the shaftl 10 is a Worm wheel 11 actuated bythe worm on the shaft 12. 13 isa clutch pulleyonrtheshaft 12 driven from any source of power, and 14 is a clutch keyed on theshaft adapted to engage The clutch 14 is actuated by the lever 15 in the manner to berhereinaftendescribed. -When the clutch is in engagement the pins 8 entering and leaving the slots 7 'cause the reel to be partially rotated to bring'the shelves in 'pro er relation to .the openings in the front of t e oven. This reel and disengage the pulleyl 13 thereoperating mechanism i's no part of my present invention. v

In the .construction herein shown I have Voven operating dev the actuating wheelsecured to the oven' shaft being omitted.v

,illustrated a machine designedto charge a shelfof an' oven with the dough, 'and also to unload another shelf of its baked'goods. In

this construction I have shown two openings in the front of the oven, 17 and 18 respectively, the o ening 17 being the opening through whic the crackers aieloaded, and the opening 15S/being ythe unloading opening.

acI

I have shown each opening'as provide with a hinge door 19 and 20 respectively, these doors beingfhinged at their upper edges so that they will turn'inward and ackward as shown- 1n Fig. 2, when the device is operated to load and unload. y 25 is a frame which supports the operating parts; which frame is constructed in any desired.V manner and is stationary in front of the oven. On this frame near the top are thehorizontal rails 27 and between these rails are the wheels 28 and 28a which form the support for a carriage 29. This carriage is a rigi frame of any desired construction which moves forward and back to and from the oven and car- -ries the loading and unloading mechanism. I have shown the carriage as comprising a longitudinal bar 30 on the en'ds of whichare ixed the wheels 28, thisl shaft being ajour- /nalefl in suitable bearings -31 in thel ends of the icarriage frame. The wheels 28 areflsecured to a hollw stub shaft journaled in bearings82 in the .ends of the frame, (Fig. -1=0)`.

the carriage 29 is-supported'the:peeler frame 35, this frame com rising-the central portion, which is lettere 35, and the two side bars 36 and 37 which extend through the portion 35 andb'eyond at. each end.- AThe ar 36 is supported on the ooved wheels I38 at the front side at each nd of the carriage 29, while thevbar 37 passes through the stub shaft of the wheel 28. and said wheel; these shafts being connectedat their ends by the end frames 40 and 41.'4 The eeler frame being thus supported is moved orward and back with the carriagefand at the same time. is free to have a' longitudinal movement upon, .the carriage, being supported 1n the manner described.

"42 is amiddlehorizontal extension of the supporting frame and it carries on its up-y per surface a guide rail which ha's the two end .straight portions 43 and 44 and the inclined middle portion 4'5.4 On the peeler frame. arev the two o posed ide rollers',46, preferably spring bac ed as s own, which in the forward movement l,of the carriage 'will enga*J e with this guide rail andcause a longitudinav movementof the peeler frame on the carriage as,

will be plainly `obvious from an inspection of The two end frames 40 and 41 have the forward extensions :47 and 48,' the extension 47 forming 'a support for `the unloading mechanism, andthe extension 48 forming a support for the loadingmechanism':

Loading mechanism-1 will first .describe A the loadingmechanism.

50 is afeed belt for the cut dough which is preferably 'fed forward 'continuously from a continuous dough cutter of any suitable con- -struction and not vherein illustrated. This belt is driven in any known and usual man` ner. I liave shown in Fig. 4 the belt as passing` over 'tlie roll 51 at the right hand end of.

the machine; this roll being journaled inthe 'stationary frame.

For convenience of description I Will refer to the extensions 47 and 48 as the unloading frame and the loading frame, respectively, as such extensions with the connecting parts in effect form such frames.

In the loading'frame andconnecting the two side bars thereofare thet'wo bars 52 and .53. Passing over `these twobars 52 and153 is a peeler belt 54 which also passes over the central roll 55 and suitable tensionrolls 5'6, 57 and 58. The resultof this constuctionis to provide a double inclined surface or peel'- l ing apron or belt passing at opposite endsl over the bars 52 and 53 as plainly seen in Fig.v

2. The roll 56 is driven and thereby the belt is likewise driven. The roll 56` has upon its end the sprocket wheel-not shown which is y engaged byhtli-e sprocket chain 59 which at its other end englages the sprocket Wheel 60 on the shaft 61.* Intermediate the two sprocket wheels-at th r` 'opposite ends of the chain 59 is the idler spij'oket 62 below the normal plane ofthe runs of chain so as to cause the chain to engage the'spirocket wheel to drive the sucl, tion roll 63 which extends between the two end frames and surroundsthe suction conduit 64 which is a stationary tube likewise eX- and seat the opposite ends into the suction conduit 64. The object of connecting at both ends is topro'du'ce' a more equal vacuum at all points of the tube- 64. Vf s The conduit 65 is connected at one/end to a vertical pipe which has the flexible por- 'tion 71 to allow for a continuous connection and still permitthetravel of the peeler back and forward to and from the oven. .In the vertical pipe 70`isa suitable valve for open.- arid closing the communication through this -pipe-orconduit., This valve is secured to the shaft 7 2'upon which is the rock arm 73 to which is attached the connecting rod 74 byi means of which the valve. is operated in the manner to be hereinafter described at the desired'intervals.

' The shaft 61 from which the peeler belt t-and`the suction roll 63 is driven is in turn driven` by the following mechanism. On its end is the bevel gear wheelv (Fig. y1) which meshes with la bevel `pinion on the shaft 75 journaled in the end frame 41. At the opposite end the shaft 75 has suitable bevel gear connection with'the shaft 76 which has a bevel pinion on itsend engaging with the bevel linion 77 on the shaft 78 at the' upper end of) the machine'. The shaft 78 is provided with the key Way 79 in which the spline on the ratchet wheel 80 engages. Journaled ound this ratchet wheel is the annular gear wheel 81 the ratchet being so constructed that as the carriage moves towards the oven the ratchet will be rotated by the gear wheel, but as tlze carriage moves away from the oven it ywi l be engaged and the shaft 7-8 be rotated. The gear wheelSJ/reshes. with Vthe rack 82 onA thestationary frame so'that the gear wheel is rotated in both the forward and backward moveme 1t of the carriage, but as described the-shaft will only be rotated as the carriage moves away from the oven.` The shaft78 being rotated, it will through the connectiondescribed rotate the driving roll 56 for the apron and the suction drum 63.

The suction valveron the shaft- 72 will be lopened and cloed by the followingmechanism. The rod 7 4 is slidingly supported on the carriage frame, (Fig. 3) and at its end it In fthe;frwardfliriovement the roller which extends beiengages the rock arnr85 on the-vertical shaft.

A back the roller wrist `on the rock arm 87 will Strike the inclined flange 90 which will cause the rock arm to move inwardly rocking the f shaft 86, the rock arm 85 andthe connecting rod 74 opening the valve. When the roller wrist reachesthe end of the' uide I88 it will be free to return to its norma position it bein actuated by the spring 91 (Fig. 3), the 'ya ve being thereby closed. Y

tion conduit 64 are the packing strips 92 arranged on opposite sides of the port 93 at one side of the suction conduit 64. These packing flanges sim ly make a tight joint upon bot-h sides of tljie port 93 between the suction conduit and the drum 63, the drum 63 being perforated at' all points. The distance between these two acking strips 92 determines t-he width-at w ich the vacuum will operate upon the out dough.

The unloading mechanism-The unloading frame has at its outer end the vacuum conduit 100 extending between' the two side frames and secured thereto. Journaled in these end frames1 and surrounding the conduit 10,0 is the suction drum 101. 1 This suction drum is of perforated material. The suction conduit 100 is provided with the port 102 and on opposite sides of this p`ort are the packing strips 103. This suction conduit, drum and packing strips are similar to those already described *for 'the loadin mechanism. Extending across between tie two side Aframes is the tapering hollow nozzle 104, the

outer edge of this nozzle extending beneath the suction drum 101i as shown 1n Fig. 2. Passing over this tapering nozzle is the foraminous apron 105. This apron at its ed es is provided with ratphet bars 106 to whic are connected a series of sprocket chains 107 which run over sprocket wheels 108 secured to the shaft 109 (Figs. 2, and 3). 'The nozzle 104 has connected into it at one or more points the air conduits 110 which connect to a common header 111 which in turn is supplied through the conduit 112 extending to the side of the unloading frame and there l`connects into a verticaly'pipe havingthe flexi` ble portion112a (Figy).

plied from any suitable source with air under- This. plpe is suppressure. Beyond the suction drum 101 is the pipe 113 provided with the inwardly tapering nozzle 114 having a sht at the apex.

This pipe 113 is connectedby-the pipe or pipes 115 with the conduit 112 which as described connects to the air supply pipe 112% A reciprocating motion is imparted to the apron 105 by the following mechanism: Upon the end of the shaft 109 is a bevel gear wheel 116 which meshes with a bevel pinion on the shaft 1 17 which through suitable bevel gears is driven from the shaftl 18 which at its upper end has a bevel pinion 119 meshing with a gear wheel 120 (Fi 1), at the upper end of the peeler. frame. he further mechanism for driving this shaft is illustrated in Fig. 10. On the shaft 120a is the sleeve 121l which'has a key Way en aged by a key or fin 122 on the shaft 120f. t opposite ends this sleeve has the opgositely toothed clutch rings 123 and 124. urrounding the sleeve 121 is .the

menta-ryt'eeth at each end for the enga e- Y f ment of the clutchrings 123 and 124. be- Between the suction drum 63 and the suc-- cured to the sleeve 125 is an annular gear Wheel 126 which meshes with the rack 82 previously described. The clutch sleeve 121 1s operated by 'a lever 127 `'which is journaled at 128, suitable connections being made between this lever and one end of the sleeve to actuate the sleeve longitudinally and at the same time permit of the rotation of the sleeve in relation-to this connection. The lever 127 is substantially a bell crank lever and is provided with the roller wrist 130 at its freeV end. This roller Wrist engages the uide way with trips so that the clutches will ethrown in and out of engagement to effect the desired operation. lIt is desired-to have the inclining run of the belt commence to travel to the leftA as the forwardedge of the nozzle 104 reaches the outer iedgeof the shelf travel of the nozzle across the shelf. lt is desired: that the belt shall not travel while tion shown in Fig. 2 to the position at w ich the outer end of the nozzle 104 reaches the inner edge of the belt 131, (this belt is a continuously moving belt for carrying ofi the baked goods), and from this point it is demovement while the nozzle 104 is traveling moving during the time that the nozzle 104 is to the inner edge' of the belt. These various startings and stoppings of the apron 105 are accomplished by the engagement of the roller wrist 130 through the following guides and trips. The roller wrist travels a ong the straight guide way 132 (Fig. 9), until it reaches the inclined guide 133.4 At this point the nozzle 104 has' reached the outer edge of the shelf 4. At this point as previously described the inclined portion of the belt has startedt'o travel to the left. During this time the roller wrist is traveling on the straight portion of the guide way 134. As it reaches the end of its travel in theguide way it passes the." spring trip 135, lifts that trip which immediately flies back behind 1t, actuated by a suitable pring, not shown, to tht position shown in ig. 10. As the unloader starts in the return movement the Sleeve 125 which is provided with comple across the belt 131 and will remain withoutl traveling from the outer edge of the belt 13,1

4 and continuezthis movement during the the unloading device is moving from the osisired that the apron 105 shall reverse its v iiected to the left, thereby bringing it into the plane of the uide-132, in the guide way 136.

- This will hol the sleeve 121 in its middle posiarm 162on the shaft 163.

. and rock the hinge portion 166 but without l tion so that bothof the heads 123 and 124' will be out of engagement with thesleeve 125. It

.will pass the spring trip 137 and will then engage the spring trip 138 which isnioved in its forward movement and will run thence over the guide 139 'during which time the belt willhave the reverse movement previously described until it reaches the inclined guide 140 passing acrosswhich it will operate the trip'141 and thence return to vthe middle or ino erative position ofthe clutches.

nthe endl of the suction' drum 101 is a gear wheel- (Fig. 3) which meshes with the gear wheel 151, which gear wheel has a beve gear wheel ,'meshing with the. bevel pinion 152 onfthe shaft 153, which-at its npper end has the spiral gear 154which meshes with the corresponding gear 155 on the shaft 118, `previously described. The lever A127 which controls the operation of the clutches 123 and 124 actuatedby the gear wheel-126, as previously described' operates this shaft 118 and therefore the rotary movement of the suction drum 101 will correspond to the movements of the. apron .105. That is, the drum will be rtated at the same times that the belt is being actuated.

Air under pressure is admitted into the pipe 112 from any suitable source, and passes through the conduits 110 ,and 115, thereby bringing air under pressure into the nozzles 104 and 114 upon oppositesides of the suction drum. The air supply to this nozzle is controlled by valves'160 (Fig. 5). This valve has connected to its actuating rock arm a connecting rod 161 (Fig. 9) connecting to the rock Below this rock arm 162 on the said shaft is a'rock arm .164 having a roller wrist thereon which in the forward movement' of the carria e is not actuated until the roller'wrist on t ie rock arm 164 reaches the outer end of the guide 165 at which point it strikes the hinge portion 166 thereon, said hinge portion being held against movement in this' forward movement of the roller Wrist on the rock arm 164, thereby causing the rock arm to be actuated rocking the'shaft 163 and opening the air valve to admit air during the further travel' of thel carriage, during which' time. the roller wrist on the rock arm 164 will ride against the guide 165.v As it reaches the end of its movement inward the roller wrist will pass the end of the'guide 165 and a suitable spring 167, (F 3), will rock the valve toits c ose position which movement will throw the roller wrist 164 inside of the guide iiange 1'65. In the outward movement of the carriage the roller wrist will impinge against actuating the valve;

ywithdraw it therefrom.

The carriage actuating mechanism.--Thc carriage 2'9is moved forward and baci; on the frame by any suitable mechanism. The mechanism I have shown for actuating the carriage consists vof vthe following: 1.71 is -a drive shaft driven from anv suitable source l of power. On this 1s a gear` wheel 140 mesn-y ing with a gear wheel`172 on the shaft 173i. Figs. 4 and 5. On the end of the shaft 1735i is acrank arm 174'wliich is connected to a around the drum 181, around a sheave 1&3v

fastened to the oven front, and has its eppo-V site endsconnected'to opposite sides of the carriage at and 186.

The rotation of the crank 174 causes a rocking movement to be imparted to the crank 175 whichrocking movement will by the cables .described impart a reciprocating movement tol the'carriage 29. This reciprocatin movement will project the loading and un oading mechanism into theoven in operative relation to the oven shelves and This forward and backward movement of the carriage :operates the clutch 14 already described and thereby controls the rotation of the reel oven. This is accomplished by the following mechanism: -To the outer endof the leve 15is connected a rod 190 which extends cn wardly and upwardly to the bell crank llever 191, Fig. 3,.to one end of which it is ccnnect-k ed. To the other end of the bell crank iever is connected a rod 192 which connects to the bell crank 193 4the other end 4of this bell crank having an actuating rod 194 which extends out on the frame opposite the path of the carriage. On the frame is pivoted a spring actuated lever 195 (Fig. 5) which is in the path-of a portion of the carriage. in this case 1 have shown it inthe path of the shaft 36. This lever is so constructcdrthat in the forward movement-of the carriage this` shaft'may strike it and the lever will yield without actuating the clutch, thelevcr preferably being made in two parts with a ruie On the shaft 176 is a drum 178 toV This seien' Vsuitable means until the wheel 9 has made la half .revolution and then by automatic mechanism itis` disengaged ready for another operation; I do no t deem it necessary to describe this -mechanism for it -is already described in another application ofv myself and Anton Mill. y

If I desire, as is necessary with lsome goods to have the oven move two shelves so as to have an empty shelf pass around the oven to get heated between baking operations, I place a second lever 198 similar to the lever 1'95 so that in the outgoing movement of the carriage the oven will be caused to be actuated'twice that is the wheel 9 will make a complete revolution and movevthe reels a space equal to the distance of two of the s elves for each reciprocation of the carrier.

Operation- The parts being thus con structed7 their operation is as follows: rlhe' cut dough in the usual sheet form comes from a continuouscutter, being fed from the cutter (not shown) along the belt 50.. The peeler being actuated toits innermost position as shown in Fig. *2, the dough will be gathered on the belt 54 in thereturn movement at which time there will be in front of the peeler a charge of cut dough or a out dough strip. As the'cross bar 52 reaches the inner edge of the belt 50 (Fig. 2) that belt traveling to the right with its upper run and y thesuction drum 63 rotating by the mechanism described, the cut dough strip will be picked up by the suction applied through the port 93 and through the perforations in the drum 63 and will be deposited upon the apron 54 each successive row of crackers being picked up in the saine way in which they rest upon the belt 50 and be'carried over the rest upon the upper surface of the belt 54. The packing strips 92 are so located as to permit the suction to'take place so as to pick up the forward edge of the cracker and as the suction drum passes over to pick up 'the rernainder thereof, and then as the forward edge of the cracker reaches a point abovethe apron it will pass the up .er packing strip, whereupon the suction wi l be released and the crackers will dro upon the apron. The guide 45 for the pee er frame will cause the -peeler not only to have an outward movee ment but a transverse movement synchro nous with the forward travel of the continuously moving cut dough strip so that the peeler will take up the cut dough during the travelthereof. 'lhe motion of the carriage is now reversed and the peeler projected into the ovenagain as shown inFig. 2, directly over,one of the shelves 3. ln the inward movement of the peeler or the loading or v charging device7 the nose thereof will strike the door 19 and cause it to open as shown in Fig. 2. When the parts have reached the position shown in Fig. 2, the belt 54 will again be actuated and as the peelei withdraws from the oven the crackers will be deposited upon the shelf 3 in precisely the same way and arrangement as they formerly rested u on the belt 50 and the door 19 will be. c osed asthe peeler withdraws to collect another oharge.

With the construction which i have shown and in which the charging mechanism is combined with the unloading mechanism, the crackers on the shelf 4 will be unloaded and pickedup upon the belt 105 as the unloading device moves inwardly from the position shown in Fig. 1, to that shown in Fig. 2. rlhis is accomplished as follows: As the carriage carrying the unloader frame moves inward the air pressure valve isopened and air will be discharged through the nozzles 104 and 114 these air currents being opposed to each other. rihe suction drum 101 will also he rotated and a artial vacuum be produced in the conduit 100. As the forward end of the nozzle 104 reaches the outer end of the shelf 4 these yopposing air currents being directly downwardly will tend to pass under both sides of the crackers and this will either partially lift the crackers or tend `to lift them 11p-against the suction drum 101 opposite the. member 102 whereupon the vacuum or the partial vacuum -in the s ace between the packing rings 103 will holt the crackers against the drum 101 and carry them up upon the apron 105 where they will be dropped as soon as the upper packing 103 is passed and the vacuum ceases to be effective. in this way all the crackers on the shelf 4 will be picked up from that shelf and carried up and rested upon the apron 105 in the same way in which they rest upon the 105 shelf. Buring the outward movement of this unloading device when the outer end of the nozzle 104 reaches the inner edge of the belt 131 the apron 105 will be driven in the reverse movement,that is the upper run will 110 -move to the right and the crackers vwillbe deposited-upon the belt 131 in the same way in which they were originally taken from the belt 59 and they may be carried on'this belt 131 to any desired point in the factory for 115 packing purposes. With this mechanism therefore the continuous strip of cut dough may be fed from a continuously operating cutter on to the belt 50, be charged upon an oven s helf of a reel oven, be then carried 120 around the oven and baked, and be removed from the shelf and delivered in the same way in which they were originally cut upon the deliverybelt which will carry them fron. the oven.

it is obvious that by the mechanism described that during the time that the loader and unloader have withdrawn from the oven the shelf 4 will be moved from a position op- Dosite the unloading device to a position op- 130 posite the loading device, or'if a--double actuating device for the oven is employed that every ot-her shelf will be loaded during the revolution of the reel.
